I am happy for you, but every time we try to do something on the Mac we mutter “geez this is so much easier on the PC.” On numerous occasions my wife has just given up and left the room. I have built 4 computers over the last 6 years for myself and friends, and I would never recommend a Mac to anyone. Style over substance. There is a reason why 85% of the world runs on MS.
Please name a specific task that is harder on the Mac than it is on the PC.
There are several reasons, including luck that Gary Kildall's wife didn't want to sign an NDA, riding on IBM's coattails, Lotus 123, backwards compatibility, illegal monopoly and market inertia.
Notice none of the reasons has anything to do with technical superiority or usability.
Two or so years ago, that figure was 96%. It's dropping daily.
